The ITCZ is visible as a band of clouds encircling Earth near the Equator. The Intertropical Convergence Zone (ITCZ / ɪ tʃ / ITCH, or ICZ), [1] known by sailors as the doldrums [2] or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge.
The reason the rain belt is situated near the tropics can be attributed to the fact that the Sun's radiation is strongest near the equator, which is located in the middle of the tropics. This solar radiation generates large amounts of heat near the equator. [1] [2] This causes the air at ground level in the tropics to warm up.
The Hadley cell is a closed circulation loop which begins at the equator. There, moist air is warmed by the Earth's surface, decreases in density and rises. A similar air mass rising on the other side of the equator forces those rising air masses to move poleward. The rising air creates a low pressure zone near the equator.
The heating of the earth at the thermal equator leads to large amounts of convection along the Intertropical Convergence Zone. This air mass rises and then diverges, moving away from the equator in both northerly and southerly directions. As the air moves towards the mid-latitudes on both sides of the equator, it cools and sinks.
In areas with a very small or non-existent Coriolis force (e.g. near the Equator), the only significant atmospheric forces in play are the pressure gradient force (the pressure difference that causes winds to blow from high to low pressure [15]) and a smaller friction force; these two alone would not cause the large-scale rotation required for ...
Both philosophers theorized the Earth divided into three types of climatic zones based on their distance from the equator. Like Parmeneides, thinking that the area near the equator was too hot for habitation, Aristotle dubbed the region around the equator (from 23.5° N to 23.5° S) the "Torrid Zone."
The disastrous Afghanistan withdrawal after 20 years of war is widely viewed as a low point in Biden’s term. He faced criticism from military families after being filmed checking his watch ...
A low-pressure area of calm, light variable winds near the equator is known as the doldrums, [8] near-equatorial trough, [9] intertropical front, or the Intertropical Convergence Zone. [10] When located within a monsoon region, this zone of low pressure and wind convergence is also known as the monsoon trough . [ 11 ]
